Bug fix for vulnerability CVE-2014-0039 reported by Murray McAllister of
the Red Hat Security Team in which an attacker-controlled fwsnort.conf
file could be read by fwsnort when not running as root. This was caused
by fwsnort reading './fwsnort.conf' when not running as root and when a
path to the config file was not explicitly set with -c on the command
line. This behavior has been changed to require the user to specify a
path to fwsnort.conf with -c when not running as root.
